Workspace Health Monitoring Gadget

<![CDATA[]]>https://greenshoegarage.com/2020/10/learning-from-covid-19/<![CDATA[]]>

Goal

An open-source device that can monitor 8+ key environmental factors that affect people's perception of a healthy and productive workspace:

  • Temperature
  • Pressure
  • eCO2
  • Humidity
  • Brightness
  • Noise
  • TVOC
  • PM 2.5um

Code and hardware is a prototype, no guarentee of any sort is implied. Use at your own risk.

Functionality

  1. Monitor 8 environmental factors
    1. Central processing of all sensor data
  2. Record the telemetry locally
    1. 24-hour rolling log
    2. Store on microSD card
  3. Display the telemetry locally
    1. Display new data point every 3 seconds
  4. Transmit telemetry to web-based cloud service
    1. Send latest sensor readings every 10 minutes
